 #### Viewing email messages
 
-  Login.gov uses a tool called [Mailcatcher](https://github.com/sj26/mailcatcher) to view email messages locally. When Mailcatcher is running, visit http://localhost:1080/ to see them.
-
-  We spin up a Mailcatcher process by default through `make run`, but if you want to run Mailcatcher as a standalone process, just run:
-
-  ```
-  $ mailcatcher
-  ```

-  If you would like to run the application on a different port:
+  In local development, the application does not deliver real email messages. Instead, we use a tool called [Mailcatcher](https://github.com/sj26/mailcatcher) to capture all messages.

-  * Run the app on your desired port like `make run PORT=1234`
+  - To view email messages which would have been sent, visit http://localhost:1080/ while the application is running.
+  - To view email templates with placeholder values, visit http://localhost:3000/rails/mailers/ to see a list of template previews.
